If you have a friend who's never seen a BL film, I'd start them off with this one because this is story is what this genre's all about. I went from gushing at the romance of the main characters to crying for the entire second half of the film. I really identified with the unrequited love aspect and having to leave your high school sweetheart behind because your parents made you move. It's unforgivingly sad toward the end, but not in an entirely unrealistic way. I want to watch it again, but I don't want to *feel* as much again and I don't think that I'd be able to control myself to be honest.
